Ok, I can accept that logic. Had to ask because the way you stated it I thought you might have a "it will burn out your drive" sort of claim... Actually I have done this, but it didn't hurt anything, ie terminators at several points, as well as running without terminators at one end. On other occasions I have done it and immediately had problems. There is a wide variation of tolerance among equipment. I have also seen setups where it was impossible to run with internal ribbon cable and external round cables, had to go to ribbon on both ends. An impedance mismatch, I guess. -- Steve Passe | powered by smp@csn.net | FreeBSD -----BEGIN PGP PUBLIC KEY BLOCK----- Version: 2.6.2 mQCNAzHe7tEAAAEEAM274wAEEdP+grIrV6UtBt54FB5ufifFRA5ujzflrvlF8aoE 04it5BsUPFi3jJLfvOQeydbegexspPXL6kUejYt2OeptHuroIVW5+y2M2naTwqtX WVGeBP6s2q/fPPAS+g+sNZCpVBTbuinKa/C4Q6HJ++M9AyzIq5EuvO0a8Rr9AAUR tBlTdGV2ZSBQYXNzZSA8c21wQGNzbi5uZXQ+ =ds99 -----END PGP PUBLIC KEY BLOCK-----
